Returns the tilt value for the y axis of the device. Imagine a line running from the bottom to the top of your device's screen.
Returns a value representing the tilt of the device.
TiltGety() will return a negative value if the device is tilted up or a positive value if tilted down. The range of values is typically between -1000 and 1000. A value of zero is returned if the device is flat on this axis. Values greater than +/- 1000 indicate that the device is being shaken.
Available in DragonFireSDK 1.0 and later.
The example below will query the current location of a text object and increment it's X and Y coordinates in the OnTimer() event.
// Set up an image of a ball to move around the screen:
BallImage = ImageAdd("Images/Ball.png");
BallView = ViewAdd(BallImage, 0, 0);
int BallX, BallY;
int tx, ty, tz;
// Get tilt (accelerometer) data for each axis.
tx = TiltGetx();
ty = TiltGety();
tz = TiltGetz();
// Update the ball's next X and Y values based on G-Force and the strength of gravity:
BallX = ViewGetx(BallView) + (tx / 100);
BallY = ViewGety(BallView) + (ty / 100);
// Don't let the ball go off the screen:
if (BallX >= 283)
BallX = 283;
if (BallX <= 0)
BallX = 0;
if (BallY >= 443)
BallY = 443;
if (BallY <= 0)
BallY = 0;
// Update the ball's position:
ViewSetxy(BallView, BallX, BallY);
